Definitions
- This application is related to the field of synthetic turf, and more particularly to methods of recycling synthetic turf and infill materials produced thereby.
- Synthetic turf has been used for years in athletic playing surfaces such as football, baseball, and soccer fields, and has more recently been used in other applications where an alternative to natural grass is desired. These applications include at least playgrounds, residential and commercial lawns and other landscaping, jogging paths, paintball fields, tennis courts, putting greens, and dog runs.
- synthetic turf includes a pile fabric having a backing and a plurality of upstanding ribbons, also called face fibers or filiform formations, resembling grass.
- Many synthetic turf products also include an infill material dispersed among the upstanding ribbons, which may consist of sand, tire rubber crumb, or other particulates, either singularly or in combination with each other. The infill material simulates the soil in natural turf, acts as a ballast, and/or contributes to the physical properties of the turf, such as resiliency, that make the turf suitable for a particular use.
- Synthetic turf has a limited useful life, the length of which depends on the construction of the turf, the application for which it is used, and how the turf is maintained.
- a typical synthetic turf for use as an athletic field may have a useful life of from about 8 to 15 years.
- a large amount of synthetic turf is currently being used in hundreds of athletic fields and in other applications.
- To avoid sending that turf to landfills at the end of its useful life there is a need for a method of recycling and reusing all or portions of the synthetic turf.
- a synthetic turf that is recyclable is also a need for a synthetic turf that is recyclable.
- Recycling of a product typically refers to converting that product into a material or product for another use or extracting at least one of the individual components or materials of the product for use of that component or material in another product.
- the recycled product may be used in a similar product, such as when paper products are recycled to make other paper products, or may be used in a completely different product, such as when tires are recycled to make asphalt.
- Methods for recycling carpet and for preparing carpet backing using recycled carpet scrap are known. Some such methods involve separating the carpet yarns, or tufts, from the backing, e.g. by cutting, and processing only the tufts to recover any nylon. In another recycling process the tufts can be spun into a new yarn for use in carpet or other textiles. One problem with these methods is that only the face fibers are recycled and the backing must be otherwise disposed of. Other methods of recycling carpets include grinding carpet scrap, including the backing, into a fine powder. The powder is then introduced into a carpet backing formulation which may be a precoat, laminate coating, skip coating, or foam coating. The formulation is then applied to a substrate, and cured by heating or drying. One problem with these processes for recycling carpet is that recycled material can make up only about 5% by weight of the carpet backing into which the recycled material is incorporated. This corresponds to approximately 2.5% by weight of a broadloom carpet.
- Synthetic turf differs in composition from carpet, and those differences in composition make conventional carpet recycling processes unsuitable for recycling synthetic turf.
- the majority of carpet products use nylon face fibers, while the majority of current synthetic turf products use polyethylene.
- the primary coating of most broadloom carpet is a latex coating, while the primary coating in most synthetic turf is polyurethane. In the United States, only a small fraction of broadloom carpet includes a coating containing polyurethane, and only a small fraction of synthetic turfs have a coating containing latex.
- Many synthetic turf products include components that are not found in carpet and that are incompatible with, or at least undesirable in, conventional carpet recycling methods.
- conventional carpet does not include infill.
- Typical infill materials for synthetic turf installations include sand, tire rubber crumb, and/or other particulates, either singularly or in combination with each other.
- recycling synthetic turf presents a unique problem not encountered in the recycling of carpet. Separating infill from the remainder of the turf may require use of special equipment, and there may be environmental concerns associated with disposing of the separated infill. Additional concerns in the recycling process are the effect of any residual infill particulates on the size reduction process and on the properties of the final product.

- Table 1 Several embodiments of primary coating and secondary backing compositions are shown below in Table 1.
- the methods described herein may be used to recycle and reuse synthetic turf, including turf described above, or other synthetic surfaces having chemical make-up similar to synthetic turf.
- Recycling synthetic turf begins with the removal of the material from the point of installation.
- the synthetic turf is installed by unrolling a 15 foot wide by 150 foot long roll of turf.
- a field typically requires multiple rolls, which are laid out on the field side by side and seamed together to form the field.
- Infill is then installed.
- the infill may be one or more of sand, rubber, and/or any other suitable material as described previously.
- When a synthetic turf is removed typically some of the infill is separated from the remainder of the infill.
- the infill may be removed prior to the removal of the turf or at the same time. For example, a machine may collect the infill and place it into a container or onto the field.
- the turf and infill may be removed at the same time by a machine or by hand.
- the turf is cut and the infill is dumped out.
- the turf is then downsized into sections (e.g. 1 by 1 foot for ease and efficiency of shipping) that can be accepted by the next process.
- the downsizing may be accomplished by hand or machine.
- the machine may be large or small and may use rotary blades or knifes or any of a variety of different methods known in the art.
- the downsized pieces, also referred to as turf fragments, are typically placed on pallets and shipped to a recycling facility.
- a plurality of synthetic turf fragments are agglomerated.
- the granules of agglomerated turf fragments are placed into an extruder.
- the granules are extruded to form an extrudate, for example in the shape of a strand or ribbon.
- the downsized pieces of synthetic turf are placed into an agglomerator.
- Suitable agglomerators include Condux agglomerators, Netplasmak NPS agglomerators, or tub densifiers.
- the downsized pieces of turf should be of a size suitable for agglomeration. A suitable size will depend on the agglomeration equipment employed. For example, agglomerating equipment such as a Condux can accept sizes of up to 2 square feet.
- the synthetic turf fragments are equal to or less than about 1 square foot. In some embodiments, the turf fragments are less than 6 square inches. In some embodiments, the turf fragments are less than 3 square inches.
- the step of agglomerating the turf fragments involves using mechanical energy to densify the components of the turf fragments into smaller and denser granules.
- some of the synthetic turf components are mechanically melted.
- no heat is added during agglomeration; however, frictional forces cause the lower melting components to melt.
- Lower melting components include any components that melt as a result of the mechanical mixing during the agglomeration process, and in some embodiments include polyethylene and polypropylene.
- Agglomeration may also include further reduction in the size of the turf fragments, and particularly of the high melting components. For example, in some embodiments polyurethane does not melt, but is reduced to a powder.
- higher softening components such as polyurethane and rubber
- the rate of agglomeration depends on a variety of factors including at least the size of the turf fragments and the composition of the turf fragments. In some embodiments the rate of agglomeration is from about 50 to about 2000 lbs/hour, or from about 100 to about 500 lbs/hour, or from about 250 to about 350 lbs/hour. In one embodiment, the agglomeration process produces granules of agglomerated material. These granules have the same or very similar chemical composition as the starting synthetic turf fragments.
- downsized material i.e. turf fragments
- Condux machine by hand or by belt into a shredder which cuts the turf fragments into smaller pieces.
- the shredder uses a rotary blade inside a steel box to cut the downsized material into smaller pieces. These smaller pieces are then transferred to a holding box where the material falls through a screen which allows through only pieces of a set size or smaller. The larger pieces are blown back to the shredder to be further downsized.
- the material passes through the screen it is fed into a screw or auger which feeds the material between two steel plates that face each other, one twists and the other is stationary.
- the plates are shaped to have room in the center and are close together at the edge which generates friction and heat to soften the material. As the material softens it combines with any other material present. The combination of materials is pushed out of the plates as a strand or in small pieces which can be further downsized if needed. No heat is added during the process; however, the material can reach temperatures ranging from approximately 250° F. to 400° F. due to the mechanical energy.
- the agglomerated pieces are transferred to a screen for sizing. Those that pass through are boxed. The larger agglomerated pieces are sent to another shredder and then collected.
- the agglomerated material may be in the form of granules.
- the disclosed method further includes the step of adding fillers, modifiers, or other additives. These additives may be added prior to or during the extrusion process. When the additives are added prior to extrusion, they are premixed with the granules of agglomerated material and added to the extruder. In other embodiments, the additives may be added during extrusion.
- twin screw extruders can efficiently mix the granules of agglomerated turf material and additives together during extrusion.
- Fillers may include but are not limited to calcium carbonate, coal fly ash, iron oxide, or barium sulfate, or other fillers known in the art.
- Modifiers, colorants, or other additives that are suitable for use with the present invention include, but are not limited to, plasticizers, elastomers, compatibilizers, colorants, antimicrobials, and UV stabilizers.
- modifiers examples include wax:, EPDM rubber; high and low density polyethylene; high and low density polypropylene; ExxonMobil VistamaxxTM 6102, ExxonMobil Vistamaxx 3000 Propylene-based elastorner, ExxonMobil Exact 9361 ethylene-based plastomer resin, and ExxonMobil Exact 9371 ethylene-based plastomer resin (all available from Exxon Mobil Chemical, Houston, Tex.); Faraprene 381-35A (available from O'Neil Color and Compounding, Jasper, Tenn.); and any number of other modifiers.
- Suitable colorants include dyes and pigments; red, green, blue, black or any number of different colors can be added. However, in some embodiments, colorants may have very little effect due to the dark nature of the material.
- granules of agglomerated material make up from about 10 wt % to about 90 wt % of the material that is extruded. In some embodiments, the amount of filler added prior to or during extrusion is from about 10 wt % to about 90 wt % of the material that is extruded. In some embodiments, the amount of filler added prior to or during extrusion is from about 10 wt % to about 70 wt % or from about 10 wt % to about 50 wt % of the material that is extruded.
- the amount of modifier added prior to or during extrusion is from about 10 wt % to about 90 wt % of the material that is extruded. In some embodiments, the amount of modifier added prior to or during extrusion is from about 10 wt % to about 70 wt % or from about 10 wt % to about 50 wt % of the material that is extruded. In some embodiments, the amount of colorant added prior to or during extrusion is from about 1 wt % to about 10 wt % of the material that is extruded.
- the step of extruding the agglomerated turf material may be carried out with any equipment suitable for extrusion.
- extruders may be used for this process depending upon the type of mixing or heating that is desired.
- suitable extruders include single screw and twin screw extruders.
- the twin screw extruder may have co-rotating or counter rotating screws and the single screw extruder has one rotating screw.
- the screws can be designed to do a multitude of things but having the capacity to heat and mix the material is essential.
- Extruders typically have variable screw speeds and variable heating as well as variable feed rates. The appropriate speed and heat rate is determined by the type of output desired.
- Extrusion is carried out at elevated temperatures.
- the temperature during extrusion is between about 200° F. and about 500° F., or between about 250° F. and about 450° F.
- the temperature during extrusion is between about 350° F. and about 400° F.
- the rate of extrusion is from about 3 to about 50,000 lbs/hour, or from about 100 to about 500 lbs/hour, or from about 300 to about 500 lbs/hour.
- Extrusion can be carried out using any size die that will provide a product of the desired size, but in some embodiments is carried out using a die that is between about 102 and about 305 mm in diameter.
- the extrudate is cut into pellets or granules.
- Suitable equipment for pelletizing includes, but is not limited to, pelletizers made by Gala Industries Inc. (Eagle Rock, Va.).
- the extrudate is cut into pellets immediately after it emerges from the die and may be simultaneously cooled using water.
- the extrudate is extruded into a water bath and is then cut into the desired size and shape.
- the final product of the extrusion step is pellets of any desired shape including, but not limited to, spherical, cylindrical, or oval/football shaped.
- the pellets may also be of an irregular shape. This irregular shape might be advantageous, for example, to aid tight packing of the granules.
- pellet sizes vary from 0.05 mm to 9 mm. In some embodiments, pellet sized vary from 1 mm to 6 mm or from 1 mm to 3 mm. In one embodiment the pellets are around 200 pellets per gram with a football shape.
- agglomerated material (granules) is mixed with a calcium carbonate filler and a modifier, Exxon 6102.
- the mixture is 50 wt % agglomerated material, 10 wt % calcium carbonate, and 40 wt % Exxon 6102.
- the mixture is poured into the feed system of an extruder.
- the mixture is heated to 400° F. and mixed at 500 rpm's.
- the duration of mixing relates to the size of the extruder and the speed of operation.
- the mixture is then pushed out of the extruder by the screws through a plate on the end of the extruder.
- the plate has a multiplicity of small holes which may vary in size from about 0.5 mm to about 15 mm, through which the material is extruded. Strands of extruded material are produced. In one embodiment, the strands are then cooled in a water bath and cut by a strand cutter producing a pellet that has irregular edges. In another embodiment, the strands are fed into a water ring which cuts the strands and drops the pellet into water. This process can produce a football shaped pellet. In another embodiment, the strands are fed into a Gala cutting system that cuts the strand underwater, which produces a round pellet of about 0.05 mm to about 3 mm.
- the disclosed method further includes the step of separating at least 90% of non-recyclable components from the synthetic turf before the step of agglomerating the synthetic turf fragments.
- Many conventional synthetic turfs include large quantities of infill materials such as sand, gravel, and rubber. These materials, however, are not generally considered recyclable and are not favored for use in the recycling method described herein. Accordingly, in some instances, it may be desirable to remove at least some of the infill, or other components, of an existing synthetic turf before subjecting that synthetic turf to the recycling method described above. Separating the non-recyclable infill or other non-recyclable components may be accomplished before or after the synthetic turf is size reduced to turf fragments.
- a portion of non-recyclable infill material is separated from the remaining synthetic turf. In some embodiments, at least 80% of the non-recyclable infill material is separated from the remaining synthetic turf. In some embodiments, at least 90% of the non-recyclable infill material is separated from the remaining synthetic turf. In some embodiments, at least 95% of the non-recyclable infill material is separated from the remaining synthetic turf. In some embodiments, at least 98% of the non-recyclable infill material is separated from the remaining synthetic turf.
- Embodiments of this invention also provide infill for a synthetic turf.
- the infill includes a material (for example particles or pellets) made from recycled synthetic turf.
- the terms particle and pellet are used interchangeably herein.
- the infill is made by a process described herein.
- the infill is a pellet or particle that is a mixture (a) polyethylene, polypropylene, or nylon or a combination thereof; (b) polyester or polypropylene or a combination thereof; and (c) polyurethane, latex, hot melt, a thermoplastic, polypropylene or polyethylene or a combination thereof.
- the pellets may include any component used in a synthetic turf, including but not limited to components used as the face fibers, the primary backing, the primary coating, and the infill as described previously herein.
- sand, gravel, and rubber are present only as impurities and make up less than about 5 wt % of the infill pellets.
- sand, gravel, and rubber make up less than 2 wt % of the infill pellets.
- sand, gravel, and rubber are not present in the infill pellets.
- the infill pellets of the present invention include: from about 19 wt % to about 80 wt % PE, PP, or nylon, or a combination thereof; from about 1 wt % to about 25 wt % PP or polyester, or a combination thereof; and from about 15 wt % to about 80 wt % polyurethane, latex, hot melt, or thermoplastic, or a combination thereof.
- infill pellets of the present invention include from about 10 wt % to about 90 wt % of recycled synthetic turf material.
- the percentage of recycled material in the final product may vary depending on the intended use for the pellets. For example, if more filler or modifier is required for a given use, the percentage of filler would be higher and the percentage of recycled material in the pellets would necessarily be lower.
- the infill functions as a ballast material. This infill may need more filler to increase the specific gravity of the pellets.
- a material to be used as an infill for a playing surface may require less filler, but may also require additives for softness. The increased percentage of additives will influence the percentage of recycled material in the infill.
- the pellets may be any desired shape.
- the pellets can be substantially spherical, cylindrical, oval/football shaped, or may be an irregular shape. Different shapes may be advantageous for different uses. For example, irregularly shaped pellets may more efficiently than regularly shaped pellets.
- the extent of packing of the pellets can affect the physical properties of a synthetic turf that includes the pellets.
- the pellets may be any desired size but is typically from about 0.5 mm to about 9 mm. In some embodiments, the infill pellets are between about 1 mm and about 6 mm, or between about 1 mm and about 3 mm.
- the pellets are elastomeric.
- the durometer, or hardness, of the pellets may be between about 50 and about 100 using Shore OO.
- the density of the pellets is between about 40 to about 400 pellets/gram, or from about 2.5 to about 25 mg per pellet.
- the pellet is a mixture of components wherein the mixture has two or more phases.
- the mixture may be a heterogeneous dispersion having a continuous phase and at least one disperse phase.
- the continuous phase includes lower melting components that have been melted and blended in a process such as agglomeration.
- the continuous phase may also be a mixture of these lower melting components and filler, such as calcium carbonate.
- the disperse phase includes higher melting components such as rubbers that are at least partially surrounded by the lower melting components of the continuous phase.
- the physical properties of the pellets described herein can be adjusted by one skilled in the art at least by varying the size of the pellets, the shape of the pellets, and/or the composition of the pellets. For example, one of skill in the art would understand that the properties of the pellet may be adjusted by adjusting the amount of filler, additive, and/or modifiers. Thus, the pellets described herein can be made to have any desired physical property and are, thus, suitable for use in any synthetic turf.
- Another embodiment of the invention is a synthetic turf that includes any of the pellets described above.
- This synthetic turf is suitable for a variety of uses, including but not limited to, athletic fields, landscaping, dog runs, putting greens, jogging paths, paintball fields, tennis courts, and playgrounds. Desired properties for a synthetic turf vary depending on the intended use of the turf. For example, depending on the intended use of the turf, one might prefer a softer surface (e.g. for playgrounds), a harder surface (e.g. for putting greens), or a surface that allows ideal ball bounce and/or ball roll (e.g. for athletic fields).
- Pellets described herein can be used to impart a variety of advantageous properties to synthetic turfs.
- synthetic turfs including the infill described herein have G-max values from about 75 to about 200. In some embodiments, the G-max values are from about 90 to 130.
- a related property is the hardness of the synthetic turf.
- One measurement of the hardness of a synthetic turf is the force reduction value, also called the kraftabbau value.
- synthetic turfs including the infill described herein have force reduction values from about 50 to about 75. In some embodiments, the force reduction values are from about 55 to about 70.
- a synthetic turf including infill pellets as described herein may also include another type of infill.
- This other type of infill may be any other infill used in synthetic turf including but not limited to sand, gravel, cork, polymer beads and rubbers.
- multiple types of infill may be mixed together in a single layer in the synthetic turf.
- multiple types of infill may be disposed in a synthetic turf individually as discrete layers. Still other embodiments may include some combination of mixing and layering different types of infill.
